It is year 2018, the world war III is upcoming between USA and China. Youare a secret agent working for the USA. The USA IGA (Information GatheringAgency) gathered three RSA enciphered messages. All messages were originatedfrom the same "clear text message", which is a symmetric key (m). With thissymmetric key there is a document encrypted. This document contains all thesecret information about the newest high-tech weapons made in China. Thisdocument was symmetrically encrypted with the CSEA (Chinese Super EncryptionAlgorythm). This algorithm is almost unbreakable.

You know, that the chinese government used RSA to encrypt the symmetric key.Your boss, general Eromzig bought a new supercomputer to factorizethe RSA public keys. Scientists say they need 2 weeks to factorize one ofthe public keys.That's why he hired you, because he thinks you can break the RSA algorithm in1 hour. Your mission is to get the symmetric key in decimal format.

The public keys which were used to encrypt the symmetric key are the following:

You are lucky, because you have everything to decrypt the symmetric key (m):You got brain, you have access to all knowledge in the world (wikipedia),you got pencil and paper, and of course a "BNC" (Big Number Calculator).When you break the code in 1 hour, you can save the world, because thechinese will not attack you, if you have their secret weapon. So betterhurry. The World needs YOU!
